Abstract: PURPOSE:To enable efficient filtration by applying two layers of silicon carbide particles having specific average particle diameters to the surface of a base material composed of sintered particles of silicon carbide having specific average diameters to form a filtering film. CONSTITUTION:Particles of silicon carbide having average diameters of 0.4-0.8 mum are applied to the surface of a base material 1 composed of sintered particles of silicon carbide having average diameters of 0.8-2.0 mum to form an intermediate layer 2 and particles of silicon carbide having average diameters of 0.1-0.3 mum are attached to the surface of said layer 2 to form a filtering film 3. In this manner, the particles forming the filtering film are prevented in advance from getting into between the particles forming the base material so that diameters of pores in the filtering film can be surely maintained at a required set value and also pressure losses in filtration can be restrained and flow rate of water can be kept at appropriate values, thereby enabling efficient filtration.

Title: Spread spectrum communication device
Inventor: AKEBOSHI TOSHIHIKO
IPC: H04B1/707
Filed: 1995-08-17
Abstract: PROBLEM TO BE SOLVED: To speed up acquisition of clock synchronism and reduce jitters in a clock by making a phase comparison between a convolution output and a code timing signal at a frequency which is double as high as a code cycle and acquiring the clock synchronism. SOLUTION: A code generating circuit 103 generates a spread code series and generates the code cycle of the spread code series and code generation timing of frequency which is double as high as the code cycle. A voltage- controlled oscillator(VCO) 106 generates a clock which drives the code generating circuit 103. A correlator 111 obtains a correlation with a received signal and a phase compactor 110 makes a phase comparison between the output of the correlator 11 and the timing signal of frequency double as high as the code cycle to acquire the synchronism. Then a phase comparing circuit 104 detects the time difference between the output of the correlator 11 and the timing signal of the code cycle and a reset circuit 105 generates code reset timing from the time difference.  Thus, the phases of the convolution output and code timing signal are compared with each other at the frequency which is double as high as the code cycle to acquire the clock synchronism.

Title: Address generating mechanism
Inventor: YAMAGUCHI YOSHIKO
IPC: G06F9/32
Filed: 1988-09-16
Abstract: PURPOSE:To shorten the time needed for the generation of an address used for the memory access and to increase branch processing speed by executing a high-speed branch microinstruction via a program counter, an address register, and a merge function. CONSTITUTION:When the execution is instructed for a high-speed branch microinstruction stored in a main memory, the low-order 4 bits of the branching destination address in the microinstruction are stored in an address register AR 7 when the microinstruction is decoded. Based on those low-order 4 bits, the contents of the AR 7 are selected by a multiplexer MX 8 at execution of the high-speed branch microinstruction. Then the selected contents of the AR 7 and the high-order bits 5 of a program counter PC are merged together in an address. This address is outputted to the main memory for memory access. While 4 bits of the output of the MX 8 are stored in a 16-bit PC 4 as the PC low-order 4 bits 6. Thus it is possible to generate an address without calculating the address via an adder 3. Then a high-speed branching operation is attained.

Title: Power feeding system for telephone terminal coping with lan
Inventor: MIYAMOTO KATSUHIKO
IPC: H04L12/44
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for an operator for manually clarifying the installation position to a network, every time the installation position of a telephone terminal is changed and to improve portability. SOLUTION: A control part 11 has a power feeding part 6 and a power feeding line 3B-1 connected with each other at activation of a power feeding system and, when it is judged that a terminal is a telephone terminal 4-1, power feeding is continued, and when it is judged that it is the terminal other than the telephone terminal 4-1, power feeding is stopped. Thus, in arranged telephone terminals 4-1 to 4-N on a LAN, it does not need to receive power feeding by way of an AC adapter individually from a commercial power source and preparation work becomes easier. Moreover, since it is possible to control N lines by a single telephone terminal detection part, a system structure becomes smaller.

Filed: 1999-08-19
Abstract: PROBLEM TO BE SOLVED: To protect a structure against damage by stripping the structure from a first substrate without using a laser light irradiation process thereby providing a degree of freedom in the selection of substrate material. SOLUTION: A diaphragm is stripped off from a first substrate 101 together with a polyester film sheet 105 and an adhesive layer 106 by setting the bonding force between the diaphragm and the polyester film sheet 105 higher than adhesion between platinum in the lowermost layer of a lower electrode 102 formed through an intermediate layer and silicon dioxide in the uppermost layer of the first substrate 101. Adhesion strength is then weakened between the polyester film sheet 105 and the upper and lower electrodes 104, 102 by irradiating the adhesive layer 106 with a UV ray through the polyester film sheet 105 which is thereby stripped off further from a second substrate 108.

Filed: 1983-12-12
Abstract: PURPOSE:To detect a peak value of information by constituting a photodetector receiving reflected or transmitted light from a recording medium by >=2 photodetecting sections at least and forming a difference of signals from each photodetecting section. CONSTITUTION:Outputs of the photodetectors 16a, 16d are added and a signal 30 proportional to the intensity of one side of a distributed pattern is obtained. Another signal 31 is obtained similarly by the photodetectos 16d, 16c. Further, a signal 33 representing the change in the entire reflected light amount is obtained by the photodetectors. A waveform risen at the zero point is formed by passing the signal 32 through a comparator 40 for detecting the zero point, inputted to a monostable multivibrator 41 from which a pulse is outputted in response to the leading. The signal 33 outputs a pulse keeping ''1'' while the spot passes through a pit through a comparator 42. A gate 43 passes through the output of the 41 by taking an output of the 42 as a gate signal. Then, a pulse is outputted when the spot is made incident to the center of the pit. This pulse represents accurately the center of the pit.

Title: Image emphasis system
Inventor: MORISHITA KOICHI
IPC: G06T1/00
Filed: 1984-11-07
Abstract: PURPOSE:To attain an image emphasis with high efficiency by dividing an image into many partial images, using the standard deviation value within the partial image for emphasis of a flat area and also using the differential value between the center picture element and the peripheral picture element to avoid the effects of noises of an edge part. CONSTITUTION:A picture X'im underwent the emphasis processing is expresses as [H(Sij)+beta(Xij)] (Xij-SIGMAXij/N)+(eSIGMAXij/N)+f, where the original image, the out-of-focus image, the emphasis coefficient and the component dependent on the density of the original image are referred to as Xij, SIGMAXij/N, H(Sij) and beta(Xij) respectively. An image 31 having an emphasized thin part is obtained as shown by 311 and 312 at flat parts 301 and 302 of the original image Xij30 by the effect of the coefficient H(Sij) dependent on the statistic amount Sij obtained from the standard deviation value. At the same time, the over- emphasization can be avoided for a clear form part of the original image as shown by 303. Furthermore the picture elements having large differences among those nearby picture elements have no contribution to the production of the picture SIGMAXij/N owing to the effect of a function F for an image containing an edge part 322 and a noise part 321 as shown by 32.
